Application filed April 15, 1925. Serial No. 23,265.

This invention relates to improvements in trucks, more particularly that class of truck which is known as afioor or trailer truck. Theobjefct of the invention is to providea compact, strong and easily assembled structure, and one containing a novel caster'construction. 1

*Thisand other objects will be more fully set forth anddescribed in the following specificationfand shown in the accompanying drawings, which,

Like numerals refer .to like elements throughout the drnvings in which 10 indicates generally the platform, formed of transverse planks .10,'t0 which .are secured -Fi' 7 is aside elevation of-thestructure longitudinal, beveled side -planks 10?, certain 1anks1:of the platform being provided with the" apertures 10 to-fit over stake-sockets hereinafter described. 1 I v r "The truck is provided with arectangular surrounding frame'memb'e'r-i 12, formed, {in the embodiment illustrated, jof-a singleangle bar, having the verti'cal 'flange 12*.and *lioriz'ontal in'wardlyydirected flange-12".

This frame member 12 is, as stated, bent to.

rectangular form, and has itsfreeeridsmeeting at the front of the truck, where. a cha n,

neled plate 13 is riveted or otherwisesecured .to th fr'aln member, thereby securingj h ends of the frame member. f

Located at' desired'interva-ls about the framemember are the stake-socket members g I h ,for exa'mpleythe beams 1 9 extendingin "15, centrally bored or apertured at 15 toaccommodate thefends of the stakes. 16,'and

members are provided'with base lugs or ears 15 which are riveted or otherwise secured tothe flange 12 of the frame member. The socket members, are providedwith the fiat vertical face15 facing inwardl' of the truck frameandat either side 'thereo are provided the ears 15%. .On theface 15 is provided a rib or seating lug 15?. f Supportedv byth'e's'e members .15 at each side of the truck are lon'gitudinally' extending angles 18 having" a flange 18 horiz'ontally and inwardly directe'd," and the other flange 18 vertically a? ranged to contact withlthe faces 15 ofthemembers 15, being secured by rivets'or the dike to the ears .15, and partially supported .by the ribs or lugs 15*, as shown Figs. 5

to'7, for example. The platform member 10 is supportedupon the flanges 18* 'of angles 18 with the apertures 10* fitting'overthe upper portions of the socket members'15. ,This

construction permits the use ofla relatively deep frame member .1 2; since by locating the supporting angles 18 intermediate. the top and bottom ;'of the frame memberi 12, the platform 10 will be locatedsubsta'ntially flush with the sides 'of the frame member I when in assembled relation thereto.

, In Fig. 8 1] have illustrated a modified scribed members 15 inathat asmall lug or Z bossY'15 1 protrudes from thelfiflt. surface thereof and extends through an aperture 18.

the previously describedforinj spaced longitudinal sillse2i0 of channeled fform inthe embodiment illustrated, being arranged with the I central web 20 "at the bot-tom, and the flanges 20 extendingverti c ally upward, therefrom. The platform ,10 may a lsobe partially supported upon the beams 19 seated in the channels 20 (see Fig 9), and to prope'rly position the. same witho th us o a exces r lvld ep' ha I may offset the endsf20, as shown 3,

straight lines over theofi'set ends 20.

Atthe rear of the, truck are' provided supporting wheels carried on any desirable .form of. construction in which the socket member ,15' differs from the previously de- After assemblythe protruding endofthe .lugl5 is rivetedor upset to secure the angle .bar'in proper assembled relation. This permits the dispensing with lugs o'r'ears 15 of I I provide upper 26 to properly .modate' the king-pin 31.

form of axle 25, suitably journaled at and intermediate its extremities, as indicated in Fig. 3, for example.

.At the front, supporting wheels-are pref crably arranged. in this type oftruclc for swivel motion, and to obtain caster plates 26, extending between one side of the frame member 12 and the adjacent channel 20, as illustrated in Fig. 4. These upper caster members are secured by belts or other suitable fastening means to the sideframe and channel, the outer ends of such caster plates being slightlvolfset at 26 to underlie thehorizontal flange 12 of the side frame member. These caster plates are preferably formed of cast metal and an annular ball-race 26 is machinedin one face thereof, to'accommodatt s the bearing-balls 27L Coactinp; witheach of the uppercaster plates 26 is a movable plate 28 having a coacting or complementary annular ball-race 28?, and provided with the bifurcatedbr spaced arms or forks 28 between which mounted the supporting wheel 29 in well-known manner. ,The plate is provided with the raised annular shoulder 282 surrounding the ball-race 28, to lie closely adjacent to the face of the caster 'ilate 26. A grease or lubricating aperture is provided in the plate Y28 and a cup 30 is threaded thereinto topermit forced lubrication in well-known manner,the space 30 between the plates 26 and 28 providing a lubricant chamber. At its central portion, the plate, 28 is provided with the raised boss 28; which is apertured' to loosely. accom 26 is correspondingly recessed at 26 to accommodate the boss 28, and this raised portion'is alsoapertured to permit extension of the king-pin therethrough, the upper being proviled with the positioning lugs position. and. hold the kingpin against undesired rotation. At its lower end,thelcing pin Slis threaded for engagement by a castellated nut 33, which is provided with the penipherally extending wide flange 33 beneath the plate 28, a cotter-pin -prev ented by the boss 34. extendingthrough thenut and king-pin.

In the caster construction shown and do-' scribed, lateral. movement of the wheelcarrying plate beyond a reasonable limit, is

28?, which will relieve the bearing-balls 27 of lateral thrust. Furtliierinore, the upper'cxtension of the boss 28 ordinrurily prevents the luljn'icating grease, orthe like, from leaking out through the king-pin aperture. unless an excess of such lubricant is supplied. I (it) Such an excess is occasionally. applied in order that the ad-' jacent surfaces of nut 33 and plate 28 may,

be lubricated. n

With the caster construction shown, the king-pin 31 will permit sufficient lateral movement of the plate 28 as to permit the this result,

movable plate,

. The, caster plate surface I frame member late 'al thrust of the wheel to be received by the boss 28 and the recess 26 in which it fits. .The extended contact surface 33 of nut 33 is ample to accommodate such slight friction as ma'y exist between the movable plate 28 and the'nut, it being only occasionally that frictional contact will exist, and that only arising from suspension of, the fork and wheel due to relative rise of the truck with respect to such wheel. Should wear occur between the balls 27 and the ball-races 28 and 26, or between the nut 33 and the platev 28, adjustment may readily-be made therefor by taking upthe' castellated nut 33 on the king-pin 3 1.

It will be 'obvious'thatthe construction described and shown above permits the ready, economical manufacture of a strong and compact device of this character. It will also be obvious that the structure shown and described issusceptible ofmodification and change," and I do not wish'to be restricted to the form shown and described, except as defined. in thc'appended claims.
